POWER LINES OF:

- Hard disk drives

- Floppy disk drives

- CD-ROMs, CD-R, CD-RW

- DVDs

FEATURES

PROTECTION OF BOTH 5V AND 12V SUPPLY

RAILS.

TECHNOLOGY.

DESCRIPTION

This device is dedicated to the protection of the

+5V power supply line against transient overvol-

tages due to surge of power rails up to the activa-

tion of the serial thermal protection element. It is

also dedicated to the protection of the +12V rail

against transient overvoltages.
